Be it known that I, JONATHAH-CHILDS, of West Troy, State of New York,have invented anew and useful instrument for the repair of any axle of acarriage that may be sprung or bent so as to affect injuriously the"movements of-any wheel revolving on the axle, either as to its trackingpr0perly,-or its proper alignment with the other'v'rhee'ls of thecarriage. I. call it a Carriage-Axle Adjuster, and'l declare thisspecification, withthe drawing formingrpart thereoi, to be a full andaccurate-description of iny invention. l 7

Whenever an axle-tree becomes 'bent, in order to straighten it by theusual method,it is necessary to detach how the carriage and thenseparate the iron from its wooden portion, in order to submit it to thenecessary treatment to bring it to its proper. shape without injury anddefac'ement of its wood and paint. This is atedious and expensiveoperation, which it is the object of my invention to avoid. The drawingrepreseiits my adjuster applied to an axle-tree. v

' Agrepresents the axle-tree; B its wooden, 0 its iron bar, connectedtogether by the clips D D. E E are the journals. Theadjuster consists oia square bar of iron or steel, G, of such length'as lnay be found mostconvenient for'pratical use]. One end, H,Vis turned up to form a smallspur to keep the body of the bar from touching the axle, the other endis pierced with an orifice to pass the stem of the adjusting screw. Thisconsists ofascrew-stem, s termin ated by a loop, L, fitted to be passedover and upon either of the journals. The-screw isjoperatedhyvnut-levei'd J and K, one above, the other below the bar'G. F is afulcrum block spanning bar G- by a groove in its lower "surface, so asto slide along the bar, and its upper surface is slightly rounded. M Nare two movable sc'rew clamps of any convenient form for service withthe instrument.

The mode of operating with this instrument is thus: In the drawing, thejournal E is represented as bent upwards, so as to prevent the propertracking of the wheel, and it becomes necessary to bend it down from itsshoulder at e. To do this the fulcrum block F is placed below the axle,as near es as is convenient, the bar G brought up'to it froin below, theloop L of the adjusting screw slipped over the end of the journal, andthe bar G secured to the axle by the clamps M, one being near'the spurl1 and the other over the block F. The screw-nut J is slacked, and"- Kturned upwards, drawing the loop L, with the end of the journal,downwards, until it has its proper range with the 'body of the axle. Ifthe journal were bent downwards then the operation. of the screw-nutsshould be reversed, K being slucked and J turned downwards, forcing theend offih e journal upwards. If the'axle be bent at a point between thejournals, the block F is to be placed atthe point of the bend nearestthe centre of the axle, and the bar Gr be adjusted so as to bring loop Lup to the shoulder e, and then the screws J andK operated as described,to bend the airle upward or downward, as the nature of the bend shouldrequire. If' the axle should be bent in a horizontal direction it wouldonly be necessary; to place the bar G, with its apparatusn in ahorizontal position, and operate it as described. i I

'll e advantages of this apparatus consist, first, in its beingapplicable to its work without the detaching of the axle-tree from thecarriage, and consequently in avoiding. the mar-ring of its point andinjury to the wood; scico'nd, in not wearing the screws of the clips byunscrewing and screwing them up; third, the great saving (if tiinennzlegrpense in doing the work. l

'What claim as mydni'ention, and desire toseeure by Letters Patent,- isiA carriage axle-adjusting instrument formed of the bar G, in combinationwith the block F, the adjusting we? S, with its nut-levers J and K, andthe clamps M and N, substantially in the manner set forth in thisspecification. I i
